Monomer composition, polymer obtained therefrom, and ocular lens

摘要

This invention has the objective of providing monomer compositions with which polymers of a superior balance of various physical properties such as high oxygen permeability, high water content and a low modulus of elasticity can be obtained. It has the further objective of providing polymers and ophthalmic lenses comprised of said monomers. It is a monomer composition in which three types of monomers specified by the values of Q = (mass of Si atoms in 1 molecule of monomer) / (molecular weight of the monomer) and of Z = (number of ether oxygens in 1 molecule of monomer) + (number of hydroxyl groups in 1 molecule of monomer) are combined in suitable weight ratios.
